The way to find out clues, is by collecting the proper cards that are listed for that clue. You can do that or you can enter a book code, to find a book clue.
The fourth clue comes with the cards in the second book. But for that matter, how do you open the fifth clue!!?? One clue comes from an ultra-rare card called "x-ray", the other clue comes from the book.
